High Intensity Interval Training - How It Works

Learning how to do High Intensity Interval Training challenges the body and improves fat loss. If you’ve read just about any fitness blog, magazine or website in recent years, then you’ll likely have come across HIIT.

High Intensity Interval Training or HIIT consists of exercising at your maximum heart rate for a short period of time and then switching to a slower form of exercise for a couple of minutes to recover before starting the whole cycle again.

What makes it so special?

Benefits Of High Intensity Interval Training

When you engage in HIIT, you start out by pushing hard and going at or near your maximum heart rate. This is what makes all the difference, as now you are depleting your body of all of its readily available energy in order to drive those fast twitch muscle fibers. This is anaerobic training and it relies on ATP stored in the muscles, as well as glycogen.

After this, you then switch to your regular exercise at around 70% of your maximum heart rate. This is a steady pace that you can maintain, that burns fat using the aerobic system and that allows you to recover and reduce the lactate and other metabolites that build up in your blood during intensive exercise.

Steady state cardio is normally something you can maintain for a long time before you start to tire out and this is why a lot of people will exercise by running at a steady pace for 40-60 minutes.


If you do this after having done high intensity training however, you will be running at a point when you have very little available energy in your muscles or in your blood. All the glycogen has been used up and thus you have to rely even more on fat in order to keep going. Your body becomes more efficient at burning fat and you see greater benefits from the short amount of training that comes after.

But this isn’t even the best bit. What’s so good about HIIT is that this HIIT afterburn effect continues for hours after you finish training. You’re now going about your usual activities with less glycogen, which means you’ll burn more fat even to do regular things like picking up a fork, or walking across the room!

Benefits Of HIIT Workouts

HIIT is also great for numerous other reasons. For starters, the explosive nature of the training means that you’re involving your fast twitch muscle cells. This means that you’ll release more anabolic hormones like growth hormone and like testosterone, leading to more growth. And because you’re not completely relying on your blood sugar, you’re not going to go into a catabolic a state and risk burning fat.

Another benefit of HIIT is that it improves your energy efficiency. Because you’re pushing your cells to make energy more quickly, they become better at doing just that – improving your health, fitness and athletic performance across the board!
